Supplied without sealing rings, this mounting kit is ideal when existing sealing rings are serviceable or are being purchased separately. Manufactured from high-strength, corrosion-resistant materials, the included hardware is engineered to withstand extreme exhaust temperatures, vibration, moisture and road salt, ensuring long-lasting reliability and dependable clamping performance.

What This Product Does:
  • Provides the essential hardware required to install the rear exhaust assembly.
  • Secures the rear silencer safely and correctly.
  • Maintains proper exhaust alignment.
  • Helps create stable, leak-free exhaust connections when used with the appropriate sealing rings.
  • Replaces worn, corroded or seized original mounting hardware.
  • Reduces exhaust movement and vibration.
  • Supports professional-quality exhaust installation.
  • Forms an essential part of rear exhaust servicing and replacement.

Symptoms Of Wear Or Failure:
  • Loose rear exhaust components.
  • Rattling or knocking noises from the exhaust system.
  • Corroded or seized nuts, bolts or clamps.
  • Broken or missing mounting hardware.
  • Exhaust movement during driving.
  • Poor exhaust alignment.
  • Difficulty securing replacement exhaust components.
  • Premature wear of exhaust mounts or joints.
  • Increased exhaust vibration.
  • Visible corrosion or deterioration of fastening components.

Why Replacement Matters:

  • Rear exhaust mounting hardware is constantly exposed to extreme temperatures, moisture, road debris and continuous vibration. Over time, these harsh conditions can cause fasteners to corrode, seize or lose their clamping force, reducing the security of the exhaust installation.
  • Reusing old hardware during exhaust replacement can result in loose connections, excessive vibration and poor alignment, potentially shortening the life of new exhaust components. Worn fixings may also make future servicing more difficult and increase the risk of broken studs or seized fasteners.
  • Replacing the mounting hardware whenever the rear exhaust is removed or replaced helps ensure secure installation and dependable long-term performance. The OE Match Mounting Kit provides factory-style fitment, corrosion-resistant construction and durable fastening performance, making it the ideal solution for Porsche exhaust repairs and maintenance.
  • Please note: This kit is supplied without sealing rings. Any required exhaust sealing rings should be purchased separately if replacement is necessary.

Holy broken bolts Batman! Even the latest generation of DFI (9A1) heads on the water-cooled engines are reporting broken exhaust bolts. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR069, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR069 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR069 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.

Kit includes anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case. Also includes our SR065D drill guide.
